I am brand new to this site and was hoping to get some a/c hose clamp info. I am installing an aftermarket a/c-heater in my classic car. The company (Coldmaster) says I can use their a/c worm gear clamps. They also give you brass ferrules. The crimping machines are too pricey for me. Any suggestions before I have a shop charge up the system when I'm finished. Obviously don't want leaks. I have been reading on this site that spring clamps might be better for uniform clamping.
Thank you,
